I loved all of the celebrity cameos and name-dropping in Glass Onion, but the more I think about it, the more I realize how it plays into the characterization of Miles and Blanc.
Miles keeps mentioning how he has hired people like Gillian Flynn, Philip Glass, Banksy, etc. to create things for him. And we get to see how Serena Williams is on-call as a personal trainer for his guests. But…
When Blanc quickly solved the mystery game Miles had set up, my first thought was that it was really contrived and not well-crafted. The Hourly Dong was minimalistic, yes, but not Glass-like. As for the Piece-of-Shit dock, it didn’t seem very Bansky-ish (at least to me). It looked more like a generic ice sculpture than anything - interesting at first glance, but not really much beyond that.
Then, we have Serena Williams literally phoning it in as a personal trainer. She’s content to sit there and read, as she’s getting paid whether or not she actually does any training.
Miles is quick to drop these names as if all of these talented people are part of his entourage, but the quality of their work-for-hire demonstrates that they don’t give a shit about him and/or actively dislike him.
In sharp contrast, we have Blanc, who is actually close friends with people like Angela Lansbury, Kareem Abdul Jabbar, etc. These people are close enough to him to play online games with him and worry about his well-being. In fact, they’re good enough friends that Blanc’s partner can complain to them about how Blanc hasn’t left the bath for a week.
All in all, it’s a little thing in the grand scheme of the movie, but it does show just how much thought has gone into the characterization of the two male leads.
